Designed for Drivetrain Use

Vespel® parts can help cut energy loss from friction, to make drivelines more efficient, durable, lighter and more robust.

DuPont offers a family of Vespel® parts, including the Vespel® SP-2515 line, which was designed for advanced drivetrain use. SP-2515 parts have a coefficient of thermal expansion close to that of mating metal surfaces, allowing exacting tolerances to be maintained under extremes of temperature variations.

In addition, SP-2515 parts exhibit a low coefficient of friction and excellent wear against aluminum. DuPont test labs have demonstrated that Vespel® SP-2515 parts can provide up to:

Vespel® thrust washer parts can be thinner and lighter than comparable metal thrust needle bearings. Not only are thrust washers themselves thinner, the shafts and housing can be reduced in length by the equivalent amount, helping to significantly reduce the transmission’s overall size and weight.

In addition, Vespel® thrust washers can rotate directly against the aluminum housing, reducing the number of parts, and potentially creating an easier, lower-cost assembly process.

Putting Science to the Test — Proven Advantages

Material characteristics that make Vespel® parts an effective choice for transmission and driveline applications include:

Lack of melting point, provides an extra “margin of safety” when lubrication is not available.

Featured

Vespel® products are made from a variety of materials (polyimides, thermoplastics, composites and chemically-resistant polymers). These products offer a unique combination of physical properties and design flexibility. Parts are available as custom parts, stock shapes, components or assemblies.

Vespel® CP parts offer an array of fiber or fabric reinforced composites for a range of unique design needs when wear and strength are key. Typically CP parts are used in aircraft bushings, washers, bumpers and seals.

It has been calculated that six of every seven liters of fuel put into a vehicle are lost to inefficiencies. Connecting inefficiencies to friction, studies have found that somewhere around 10 percent of this lost energy is attributed to friction between moving parts.

Low friction plastic applications developed in collaboration with DuPont experts can help improve durability and performance, reduce maintenance, and can even contribute to reduced use of fossil fuels.
